How to Determine Your Ring Size

  1. Eva Diamond Sizing Set: When ordering, you can request our complimentary sizing set for precise measurement at home.
  2. Existing Ring Method: Measure the inner diameter of a well-fitting ring. For instance, an 18mm inner diameter corresponds to size 18 on our website.
  3. String or Paper Technique: Wrap a string or paper strip around your finger, mark where it overlaps, and measure the length.
  4. Eva Diamond Printable Chart: Use our printable ring size guide. Ensure your printer settings are at 100% for accuracy.
  5. Professional Measurement: Visit any Eva Diamond store for expert sizing assistance.

Eva Diamond Tip: For the most accurate measurement, size your finger in the evening when it's likely to be at its largest due to natural daily swelling.

Expert Advice for Accurate Sizing

  • Consider seasonal changes: fingers may be smaller in cold weather.
  • For wide bands, you might need to go up a half-size for comfort.
  • If between sizes, it's generally better to choose the larger size.
  • For rings with large stones or unique designs, consult with our Eva Diamond experts for the best fit.

Factors Influencing Ring Size

  • Temperature Variations: Heat can cause fingers to expand, while cold may cause them to contract.
  • Weight Fluctuations: Significant changes in weight can affect your ring size.
  • Pregnancy: Expectant mothers often experience swelling in fingers. Consider a temporary resize or wearing your ring on a chain.
  • Aging: Over time, knuckles may enlarge while fingers become slimmer.
